WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 618,084, dated January 24, 1899.

Application filed March 23, 1898.

To all whont it may concern.-

Be it known that I, GEORGE WV. GOLDEN, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in lVindow Screens, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to that class of window-screens in which two screens, together covering the entire window-space, are slidingly secured to the blind-stop of the casing and are capable of being raised or lowered without interfering with the operation of either the window-sashes or the blinds.

The invention consists in the peculiar construction of the rail or strip forming the sides of said frame; further, in the manner of joining these strips to form the frame and of securing the screen fabric thereto; further, in the manner of securing said screens to the casing, and, further, in the peculiar arrangement, construction, and combination of parts, as more fully hereinafter described and claimed.

In the drawings, Figure l is a sectional perspective view of a portion of a window-casing to which my screens are applied. Fig. 2 is a horizontal section through one of the side strips of the screen-frame and the securingstrip for the same on the casing. Fig. 3 is a cross-section of the blank for forming the rails, partially formed. Fig. 4 is a perspective View of the ends of two adjoining side strips detached. Fig. 5 is an elevation of said strips secured together to form a corner of the frame. Fig. 6 is a perspective view of Fig. 5 looking from the other side.

The strips or rails A, of which the frame is composed, are formed of sheet metal, preferably of a non-corrosive character, such as sheet copper or zinc, the blanks being folded or crimped, so as to form the longitudinal ribs a, l), and c, the rib 0 extending on the opposite side of the blank from the ribs CL and b. The blank is then folded at its longitudinal center d, so that when the sections a and f on opposite sides of said fold are brought together the rib 0 will fit into the groove of the rib a. The bars A, however, are not first formed with the sections 6 and f pressed to- Serial No. 674,909. (No model.)

gether, but are left open at a greater or less angle, as shown in Figs. at and 6, until after they have been joined to form the frame. To join these strips together after being cut to the proper length, the ends of the adjoining strips are. formed, as shown in Fig. 4, by slotting the ribs a, b, and c of one strip transversely at g, 71, and h and the corresponding ribs of the other strip longitudinally at their bases, as at 2", a portion of the body of said strip being cut away beneath the slot to allow the ends of the rib to project and form the tongues] and 713. The two strips are then placed together, with the tongues jJt of one strip passing through the slots g h, respectively, of the other strip and the inner edge Z of the latter entering the slot i. The parts are thus firmly secured together by soldering or brazing, with the sections f extending at an angle to the sections 6, as shown in Fig. 6. After the four sides of the frame are thus secured together the screen fabric B may be laid over the sections 6 of the frame, with its edge extending beyond the grooves formed by the ribs a and b. The section f of the strip at the right of Fig. 6 is then pressed down, the rib c pressing the fabric into the groove of the rib a, and thus drawing it tightly across the frames and firmly securing it in place. The edgel of the strip at the left of Fig. 6 is slotted, as at Z, to permit the passage of the rib 0 into the groove a. The section f of the left-hand strip is then pressed down, the tongues j and k of the right-hand strip entering the slots h of the left-hand strip. The overlapping ends of the sections f may then be soldered together.

A screen thus formed will possess great rigidity and can be made of comparatively slight thickness, so that two frames may easily be placed in a space equal to the width of the blind-stop. dow-casing, I preferably employ the strips 0 of the same width as the blind-stop, having the parallel grooves D and E formed therein adapted to receive the folded edges (1 of the side rails of the frame and spaced far enough apart to permit one frame to just clear the other.

Although I preferably form the strips A with the two parallel ribs or and b, it is obvious that the latter rib may be omitted; but

To secure the screen to the winframes formed of such strips would not be as strong as when formed in the manner described, the rib b not only imparting additional strength to the bar, but also strengthening the corner connection.

lVhat I claim as my invention is 1. A side rail for screen-frames comprising a strip of sheet metal folded upon itself to form two sections, one section being crimped to form therein a rib, and the other section being crimped to form a rib extending into the groove formed by the first-mentioned rib.

2. A screen comprising frame-rails formed of sheet-metal strips folded to form a front and rear section each bent to form a longitudinal rib, the rib of one section projectinginto the rib of the other section, and the screen fabric the edges of which project between said sections and are held by said ribs, substantially as described.

3. A screen frame comprising side rails formed of strips of sheet metal each doubled to form a flat double outer edge adapted to slidingly engage in a guide-groove, and each provided with registering ribs projecting at an angle to the strip, and a-screen fabric held between said ribs, substantially as described.

4. In a metallic frame, the combination of a strip bent to form a longitudinal rib projecting at substantially right angles to the body of said strip, said rib being slotted longitudinally at one end, a second strip also provided with a longitudinal rib slotted transversely near one end, said strips being secured together at an angle, with the body of the second strip located in the slot in the rib of the first strip and the rib of the first strip located in the transverse slot in the rib of the second strip, substantially as described.

5. In a metallic frame, the combination of a strip bent to form a plurality of longitudinal ribs projecting at substantially right angles to the body of said strip, said ribs being slotted longitudinally at one end, a second strip also provided With a like number of longitudinal ribs slotted iJIQJISXGI'SBIy near one end, said strips being secured together at an angle, with the body of the second strip located in the slots in the ribs of the first strip, and with the ribs of the first strip located in the transverse slots in the ribs of the second strip substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
